Application prospect of flame-retardant acrylic pressure sensitive adhesive

With the increase of the demand for acrylic pressure sensitive adhesive, more and more attention will be paid to its flame retardant research, with characteristics, new, high efficiency, environmental protection of flame retardant and flame retardant system as the focus of research. The research on green flame retardant additives should focus on the development of new environment-friendly low-smoke, low-toxicity halogen-free products, the use of non-toxic and harmless raw materials, solvents, and catalysts in the production process, the use of environment-friendly chemical reactions.

• Halogen-based flame retardants will eventually be replaced by new, high-efficiency, low smoke, low toxicity, halogen-free products. Because of their excellent flame-retardant properties, physical properties, non-toxic and pollution-free, the carboniferous and carboniferous promoting flame retardants and inorganic polymer nanocomposites will be the focus of research and development.
• Phosphorous flame retardants and inorganic hydroxides will be further studied in the fields of microencapsulation technology, super refinement technology, surface modification technology, and synergistic effect between various flame retardants.

Development of bulk flame retardant acrylate pressure sensitive adhesive

More and more attention will be paid to the development of bulk flame retardant acrylate pressure sensitive adhesive by adding flame retardant groups. The composite technology of flame retardants is also one of the essential ways to achieve high-efficiency flame retardants. The synergistic effect produced by the composite use of organic flame retardants and inorganic flame retardants will be the resistance reaction (protection of amino group), nitration reaction, acid hydrolysis reaction, reduction reaction, and neutralization reaction of synthetic materials to get the ideal target product 3.3’4.4 ‘-tetromino diphenyl ether, the melting point of 152.8℃; There is only one sharp single peak in DSC map, which has high purity. There was an obvious triple amino absorption peak in the FT-IR map.

Therefore, it is certain that the resultant product is 3.3’,4.4 ‘-tetromino diphenyl ether. TADE and terephthalic acid can be polymerized in the system of polyphosphoric acid and P2Os to obtain high molecular weight polybenzimidazole resin, which can be used to manufacture PBI films, adhesives, coatings, and composite materials, especially in the field of fuel cell film production which has been rising in recent years.
